A threaded rod is a long, cylindrical piece of metal that has continuous threads running along its length. These threads allow the rod to be easily screwed into nuts or other materials, making it useful for various construction and engineering applications. Threaded rods are commonly made from materials like steel, stainless steel, or plastic, depending on the required strength and resistance to corrosion. Threaded rods are often used in conjunction with nuts and washers to create strong connections in structures, machinery, and furniture. They can be cut to specific lengths and are available in different diameters and thread pitches, making them versatile for many projects.
